Specification of Letters Patent.

Patented Sept. 24, 1918.

Application filed .Tune 15, 1917. Serial No. 174,997.

To all whom it may concern:

Be it known that I, FRANCIS M. STACK- POLE, a citizen of the UnitedStates, residing at Worthington, in the county of Marion and State ofWest Virginia, have invented certain new and useful Improvements inLine-Levels and Squares, of which the following is a specification.

This invention relates to new'and useful improvements in tools and theprincipal object of the invention is to provide a combined line leveland square.

Another object of the invention is to provide means for removablyholding the level on the square.

A further object of the invention is to provide the level with meanswhereby the same can be easily and quickly arranged on a line.

Another object of the invention is to provide a device of thischaracter, which is simple and durable in construction, reliable andeflicient in operation and one which can be manufactured and placed uponthe market at a minimum cost.

The invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings, wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a front View of the invention.

Fig. 2 is an end view thereof with part of the square shown in section.

In these figures 1 indicates the'frame of the level having its lowerpart bifurcated to provide the members 2 and 3 and these members receiveone arm of a square 4 between them. Each member consistsof the end bars5 having their lower ends connected by the curved bar 6 and the crossbar 7 connects the two end bars together intermediate their ends. Theend bars 5 of the two members are respectively merged at their upperportion to form the level carrying part and have hooks 8 formed at theirextreme upper ends to engage the wire 9. Intermediate the ends of theunbifurcated portions of the end bars is located a pair'of bars 10 whichcarriesthe tube 11 forming the level. One of the cross bars 7 carries ascrew 12 for clamping the device on the square.

By suspending the device on the line by means of the hooks 8 thetrueness of the line relative to the horizontal plane will be indicated,and when the square is used the level will indicate the position of thesame relative to the horizontal or Vertical plane.

It is thought from the foregoingthat the advantages and novel featuresof my invention will be readily apparent.

I desire it to be understood that I may 7 make slight changes in theconstruction and in the combination and arrangement of the severalparts, provided that such changes fall within the scope of the appendedclaims. 7

I claim as my invention: 1. The herein described line level comprising aframe consisting of two end bars forked at their lower portions andhavingv hooks at their upper extremities, a pair of side bars connectingthe fork arms, a set screw through one of said bars, bars connecting theshanks of said end bars, and a level carried by and between thelast-named bars.

2. The herein described line level comprising a frame consisting of twoend bars forked at their lower portions, a pair of side bars connectingthe fork arms and spaced for the reception of one arm of a square, barsconnecting the shanks of said endbars, and a level carried by andbetween the lastnamed bars. I

In testimony whereof I afiix my signature in presence of two witnesses.

FRANCIS M. STACKPOLE.
